AI agents use redeem_invite to create or modify resources in Agentcash. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call redeem_invite repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agentcash.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Use get_balance after to verify funds, or list_accounts if you need the per-network deposit links as well.. It is categorised as a Write tool in the Agentcash MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Agentcash MCP server in PolicyLayer and add a rule for redeem_invite: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Agentcash. Nothing to install.
redeem_invite is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the redeem_invite rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for redeem_invite. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
redeem_invite is provided by the Agentcash MCP server (agentcash). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
